Mission-driven
Online security is critical to everyone's privacy, online and offline. Account hijacking leads to breaches of personal data, leaks of valuable and sensitive information, social media impersonation, and results in billions of dollars in damage each year.
How do you know which security solution is best for you? Should you evaluate tools based on trust or brand reputation alone — or perhaps on a reliable source of information, including source code?
That is why we created the 2FAS project — an initiative that adheres to the values of transparency, privacy and security. The 2FAS apps are designed to meet everyone's needs while remaining free, accessible and easy to use.

Contributors
The project is developed with the support of an awesome group of contributors that regularly improve the 2FAS app codebase, content of our application and build the 2FAS community.
Do you want to contribute to the 2FAS project?
We are giving the world the 2FAS apps completely free. If you believe in keeping the Internet safe, open and secure for everyone, we would greatly value your contribution!
There are several ways for you to contribute to the 2FAS project:
- Check the 2FAS source code.
- Commit code changes.
- Increase security by finding and solving vulnerabilities.
- Translate the 2FAS app to new languages.
- Popularize the 2FAS app (Social Media / other channels).
- Help other users with 2FA and the 2FAS apps-related problems on our Discord server.
- Support other users by creating documentation and helping to overcome difficulties.
- Update and expand the service’s icons database.
- Donate to the 2FAS project.
